Pioneer Develops First 16-Layer 400GB Blu-ray Technology

Pioneer has succeeded in developing a 16-layer read-only optical disc with a capacity of 400 gigabytes for the first time in the world.

Its per-layer capacity is 25 gigabytes, which is the same as that of a Blu-ray Disc (BD). The technology can be also applied to multilayer recordable discs, Pioneer said.

For multilayer optical discs, it has been difficult to obtain clear signals from each recording layer in a stable manner due to crosstalk from adjacent layers and transmission loss. Utilizing the optical disc production technology that it has developed in the DVD field, Pioneer solved these problems by using a disc structure that can reduce crosstalk from adjacent layers, resulting in a 16-layer optical disc that can playback high-quality signals from every layer.

As for the read-out system, Pioneer achieved stability in the playback of recorded signals by employing a wide-range spherical aberration compensator and light-receiving element that can read out weak signals at a high signal-to-noise ratio in the optical pick-up mechanism. Since the optical specifications of the objective lens, such as NA (Numerical Aperture), are the same as those for the existing BD discs, it is possible to maintain compatibility between the new 16-layer optical disc and the BD discs.

Pioneer will present the details of this research at the International Symposium on Optical Memory and Optical Data Storage 2008 (ISOM/ODS2008) to be held in Hawaii from July 13.
